But that’s not all it was! In true Gaga manner, the singer arrived in an over-the-top array of black beads and crystal-bedecked tulle topped off with a fur stole. Once there, she climbed inside a three-story version of the “Fame” bottle and made herself comfortable, playing with her iPad and even, um, relieving herself inside a champagne bucket (seriously, Gaga?).

Then, she promptly “fell asleep,” letting partygoers including Marc Jacob, Alexander Wang, Jason Wu, Olivier Theyskens, Lindsay Lohan, and Paris Hilton stick their hands in and touch hers, as long as they didn’t wake her. She titled this strange piece of performance art “Sleeping With Gaga.” Want to see it in action? Check out this video and marvel at the wackiness!

After her slumber, Mother Monster stripped down to her lingerie—and had L.A.-based tattoo artist Mark Mahoneytattoo a small cherub on her recently shaved head in full view of the crowd:

Jason Wu’s response to the performance was a wry, “Lady Gaga is full of surprises”—and we have to agree. All in all, this was a true Gaga party; you would never expect these things to happen, but you’re never too surprised when they do!
